Skylight replacement in Strabane: what is involved?
For Strabane homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
We work across County Tyrone, including Strabane, and in neighbouring towns such as Derry/Londonderry and Omagh. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Like-for-like size replacement
- Upstand rebuild and insulation
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Roof window replacement in pitched roofs
- Usually done in a day
- Cures most chronic leaks
Things we check at survey
- Upstand and roof condition decide the scope
- A replacement is a chance to meet current thermal standards
Planning and building rules for Strabane
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight replacement in Strabane
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need to be at home for the survey in Strabane?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Strabane?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
